Dear Editor, The proton-activated chloride (PAC) channel (also known as acid-sensitive outwardly rectifying anion channel, ASOR) plays critical roles in acid-induced cell death and endocytosis.1,2 The structural investigations revealed that three protomers construct one PAC channel.3,4,5 PAC’s three captured states (resting, activated, and desensitized) uncovered the gating and proton-sensing mechanism.3,4,5 However, little is known about the regulatory factors of PAC.6 This is a preview of...

AbstractThe subcortical maternal complex (SCMC) plays a crucial role in early embryonic development. Malfunction of SCMC leads to reproductive diseases in women. However, the molecular function and assembly basis for SCMC remain elusive. Here we reconstituted mouse SCMC and solved the structure at atomic resolution using single-particle cryo-electron microscopy. The core complex of SCMC was formed by MATER, TLE6 and FLOPED, and MATER embraced TLE6 and FLOPED via its NACHT and LRR domains.
